MYER KAMENSTEIN, OF NEW YORK, N. Y.

ASH-SIETER.

Specification of Letters Patent.

Patented June 5, 1917.

Application led November 25, 1916. Serial No. 133,286.

To all fio/wm t may concern:

Be it known that I, MYER KAMENSTEIN, a citizen of the United States, anda resident of New York city, in the county and State of New York, haveinvented certain new and useful Improvements in Ash-Sifters, of' whichthe following is a specification.

This invention relates to an ash sifter of novel construction, and moreparticularly to novel and eflicient means for connecting the operatingshaft to the wire mesh drum.

In the accompanying drawing:

Figure 1 is a longitudinal section of an ash sifter embodying myinvention;

Fig.v 2, a cross section on line 2 2 Fig. 1.

Fig. 3, a perspective view of the seaming strip;

Fig. 4, a perspective view of the shaft coupling strap, and

Fig. 5, a cross section through the drum joint.

The sifter comprises essentially, a hopper 1 which communicates with oneof the open heads 2 of a casing 3, the other open head 4i of whichcarries a hook 5, from which a pail adapted to receive the sifted coalmay be suspended. Casing 3 is open at the bottom and is mounted on aflanged annular base 6, by which the device may be mounted upon a barreladapted to receive the ashes. Through casing 3 extends an inclined shaft7 journaled in hopper 1 and head 4: and furnished at one end with acrank handle 8. Shaft 7 extends axially through a correspondinglyinclined wire mesh screening drum 9, and is connected to said drum by apair of straps 10 and 11, which extend diametrically across the latterat right angles to each other. Of these, .strap 10 is furnished with acentral aperture for the accommodation of shaft 7, and has bent endswhich are riveted to one of a pair of bands 12, encircling therespective ends of the drum. Strap 11 extends with its flat faces atright angles to the shaft and is provided at its center with a laterallyextending integral bulge or U-shaped loop 13, the web or central memberof which is apertured as at 14 for the reception of shaft 7, thatextends longitudinally through the loop. The two opposed sides of theloop are likewise apertured as at 15, for the reception of a cotter pin16 which also passes through an alined transverse aperture of shaft 7.The two perforated ends of strap 11 are bent outwardly and are rivetedto the second band 12 of drum 9.

By the construction described, the drum is coupled to the shaft in asimple manner, and will be positively taken along by the latter, evenunder the severe strainto which drums of this class are subjected whenin use.

The two longitudinal edges of drum 9, face each other and are connectedby means of a binder, more fully shown in Figs. 8 and 5. This binder iscomposed of a strip of sheet metal 17 which extends from end to end ofthe drum. Strip 17 is so bent as to form above its inner face, a pair ofopposed doubled flanges 18, each of said flanges forming between itswalls an outwardly directed narrow groove or pocket 19. The two abuttingedges of the drum, are inserted into their respective grooves so as tobe straddled by the flanges, and then strip 17 is riveted to the bands12 as at 2O so that in this way, the drum becomes seamed in a simple andreliable manner.

I claim:

1. A shaft bearing comprising a strap having a laterally extendingintegral U- shaped loop provided with a pair of parallel apertured sidesand an apertured end, a shaft extending longitudinally through said loopand passing through said apertured end, a pin engaging the shaft andpassing through said apertured sides, and a rotatable member carryingthe strap.

2. A shaft bearing comprising a strap having bent ends and a laterallyextending integral U-shaped loop provided with a pair ofparallelapertured sides and an apertured end, a shaft extendinglongitudinally through said loop and passing through said apertured end,a pin engaging the shaft and passing through said apertured sides, arotatable member, a band carried by said member, and means forconnecting the bent ends to said band.
